METHOD OF MAKING SHOES.

Specification of Letters Patent.

Patented Mar, Mi, 19155..

Application filed June 14, 1913. Serial No. 773,753.

. ing is a specification, reference being had lid therein to the accompanying drawing.

This invention relates to improvements in the method of making shoes and is embodied in the steps presently to be described and claimed.

The object of the invention is that of simplifying the method of making shoes, cheapening' the construction of the shoe,

while preserving its strength and durability,

and avoiding the necessity of turning the shoe or parts thereof orof providing what is nov commonly known as a welt shoe.

The method comprises generally the lasting of a lining 'toan inner sole, the lasting of an upper to the lining and inner sole, and application to the lining, upper and. inner sole of the outer sole.

In the accompanying drawing is shown the various steps for the completion of the seam or shoe wherein,

till

Figure 1 shows a section through the last, the inner sole, and the lining, Fig. 2 is a similar view showing the application of the upper, while Fig. 3 shows the finished article. Y

Tn practising the process, an innersole B is temporarily secured to the bottom face of a last A. This inner solo is provided withva flexible edge part C of a width to extend beyond the edge of the inner sole and occupying a position on the bottom of the inner sole. Tn building up the shoe, the inner sole is placed against the last with thetapes or flexible parts thereof presented outwardly. The lining E is then drawn tight around the last'and its edges are attached by a line of stitches e to the flexible part of the inner sole and below and inwardly beyond the edges of the inner sole. This forms a firm connection between the inner sole" and'the lining and results in the stretching and roper positioning of the lining on the last.

he upper F is then stretched over the last and lining, drawn down below the edge of.

the inner sole, and is connected by a line of stitches f to the lining, and the flexible part 551' of the inner sole'at a point close or adjacent to the other line of stitches. In this condition, the outer sole C is applied, the same being placed against the inner sole while the outer edges of the flexible part, lining and upper are bent upwardly horizontally, the lining and the flexible part underlying the edge of the upper. Conveniently a welt G is then applied and the four members are next united by a line or lines of stitches g. I

In the finished article produced by the method, it will be observed that the union -between the lining, inner sole and upper are suchas to maintain the upper in its proper condition and position directly under the edge of the inner sole, while the edges of the upper are strengthened or reinforced by the underlying flexible parts of the lining and inner sole.

It will be observed that the method above described represents. a series of steps which canbe performed by 'machines or means without the necessity of turning the shoe or parts thereof, and that the union between the parts is very strong. The finished article is one that has the appearance of an ordinary shoe, while the expense of production is from a comparison much less than that of the ordinary methods heretofore employed. v

The novel shoe produced by the process herein described is made the subject matter of a copending application, Serial No. 773,752, of evendate herewith. The broad process which involves the securing of the lining of the'shoe to a lip or welt along the edge of the innersole is described and claimed in my copending application Serial No. 768,973, filed May 21, 1913.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

l; The method bf making shoes consisting in supplying an inner sole with a flexible of making shoes consisting in providing an inner sole with a flexible attaching part on its under face adjacent to its edges, lasting a lining to the said flexible part below the edge of the inner sole by a line of stitches, placing an upper on the lining and securing the edges of the upper to the lining and to the flexible part below the edge of the inner sole, projecting the edge of the upper outwardly, placing an outer sole in position, placing a Welt on the edge of the upper, and uniting the welt, upper andouter sole.

3. The art of making shoes consisting in providing an inner sole with a flexible edge portion, uniting the edge of a lining to said flexible edge portion, uniting the edge ofan upper to the lining and to the flexible portion, and connecting the upper, lining and flexible edge portion to the edge of the outer sole. y

In testimony whereof I aflix my signature in presence of two witnesses.
